53 Claims.

This invention relates to automatic packaging machinery, and particularly to mechanisms for packaging semi-liquids.

'I'heinvention broadly includes a novel method and apparatus to produce packaged food products, such as cheese, ice cream or the like, and comprises equipment to form a wrapper in package shape, which said wrapper is supported in a rigid pocket or mold, apparatus for depositing a predetermined quantity of the food product in semi-liquid consistency into said wrapper, apparatus for closing said wrapper, and apparatus for chilling the same in order to harden the product, whereby the same contracts and permits the completely wrapped food product to discharge from the pocket or mold.

The object of the invention is to provide mechanisms for completely enclosing a predetermined quantity of semi-liquid material in a thin pliant wrapper and then solidifying such material while holding the same against deformation.

Another object of the invention is to provide mechanisms for accomplishing the above object automatically, and without the necessity for any hand operations.

Still another object of the invention is to provide a package retained in its folded form, so that none of the semi-liquid material can escape therefrom before hardening.

A still further object of the invention is to provide means for solidifying the semi-liquid material while holding the formed package to prevent deformation.

According to the invention, the apparatus comprises means carrying material from which the container is to be formed, means for withdrawing a predetermined amount of said material, means for severing said withdrawn material, plunger means for passing the severed material through forming dies which fold the bottom and sides of said material and deposit the cup thus formed in a tray having pockets to receive said partially formed container,- predetermined quantity dispensing means for depositing semi-liquid material into said cup-shaped container, die means for folding the upper end of said container material, whereby the semi-liquid material is completely enclosed by said container, means for smoothing down the folded upper ends of said containers, and refrigerating means for hardening the material in said container.

Figures 15 and 16 are like views showing the manner in which the final folds are placed in the top of the container,

Figures 17 to 24 are perspective views showing the progressive steps of folding the container.

Referring to Figure 1,. the apparatus broadly comprises a table 26 having a side frame 21 supported by standards 28 which res upon the floor.

Mounted on this table are the means A for pro-' ducing the cup-like container having an open top which is deposited in the pockets in trays, as later explained. A hopper B containing the semi-liquid material to be dispensed into these cup-shaped containers is mounted on side cast ings 29, secured to the side frames 21 of the table. Beyond the hopper and its attendant mechanism is the apparatus C for folding the tops of the cup-shaped containers and smoothing the same down.

D represents a chilling or refrigerating apparatus, and this apparatus may comprise either a cold liquid bath or cold air blast for solidifying the material within the closed container. No special apparatus has been shown because these are old in the art, but the invention includes any apparatus which will chill and solidify such ma-- terials as cheese, ice cream or the like.

Container material feeding and cutting mechanism Referring now to Figure 3, the material for crank is fulcrumed on the shaft 38, and its other arm I! has an idle roller 4!, which is engaged by the cam 42 mounted on the shaft 43. This shaft 43 has a sprocket wheel 44 for receiving a chain 46, which passes over a like sprocket 41 on the main auxiliary shaft 48. This main auxiliary shaft 48 is driven by the main shaft 49. Spinning of the roll 3| may be prevented by any suitable tension device, such as that indicated by the numeral 50. After passing over the idling rolls 1! and 36, the slack container material 5i,

which has been pulled out by the operation of the bell crank, passes up over another idling roll I2, and lies upon a plate 53, and beneath a snubber 54, and between positioning clips 56 where, in the ordinary operation, it is grasped by gripping fingers 51 and 51 and wrenched in the direction of the arrow K a sufilcient distance to provide material for the formation of a single container. This snubber is mounted on the end of a rock arm 58 iulcrumed at 59, while an arm OI also fulcrumed at 59 has its end connected with a link 6| whose other end is pivotally mounted on a lever 82 mounted on the shaft 38.

The operation of this snubbing mechanism is such that when the gripping fingers 51 and 51 are moved in the direction of the arrow K, as hereinafter explained, the snubber 54 will be raised, and at the time or just prior to the time that the gripping fingers 51 reach the end of their stroke, the mechanism of the snubber opcrates so that the snubber is lowered and prevents any further withdrawal of said material.

The gripping finger 51 is connected to the sliding member 63 which has upstanding bifurcated arm 04 in which the gripping lever 66 is pivotally mounted. This gripping lever has the gripping finger 51 at one end of the same, while the other end is offset, and provided with an idle roll 61 on the end thereof.

The mechanism thus described, with the exception, of course, of the shafts, cams, etc., will be repeated six times, as shown in Figure 2. These mechanisms are staggered in order that the trays which have six pockets aligned laterally may each be provided with a partially formed container at each cycle of the machine. For convenience sake, these trays shown in Figure 1 at it may each have eighteen pockets, six in width and three in length, and as the trays are fed through the machine, as hereinafter explained, they will be practically continuous, and the rolls of container material will all be fed out simultaneously, but the extensions of the slack portions M will be of different lengths, and in staggered relation, such as shown in Figure 2. The clips 56 and gripping fingers 51 and 51 will, therefore, also be in staggered relation, and Figure 2 shows two of these arrangements, although the machine itself as constructed is provided with six. This number, however, is optional, as any width of machine with varying numbers of pockets may be provided.

Each of the members 63 is provided with a link '9 which is bolted onto the bifurcated arm 64 of the member 63 at its one end while its other end connects with the rod II. The ends of the rod II are fastened in pads I2 on one end of a lever II. The other end of this lever 13 is fastened to the shaft I4. This shaft 14 is provided intermediate its ends with a lever 16 whose lower end has a pad I1 with an elongated slot 'Il' therein. Fitting within the slot ll is a stud 11' on the end of a cam operated crank 19. This crank has its lower end slotted as at 8| to receive the shaft 48, and is provided with followers 82 and 83 which engage the heart cam 84 for reciprocating said crank. As this crank 19 is reciprocated, it will, through the connection of the levers l6 and 13 with the rods ll, operate to reciprocate the link 69, which said link is fastened at its forward end to the bifurcated arm 64 of the member 63. Pivotally mounted midway its ends is a rail 86 against the lower surface. of which the idle roll 61 of the gripping lever 85 rests. An arm 81 is secured to the rail 86, and its outer end is pivotally connected to a link 88 whose other end is pivoted to one arm of a bell crank 89, which said bell crank is fulcrumed on the shaft 14 while the end of its other arm BI is pivotally connected to a slotted crank 92, which is similar to the crank 19, and which said crank has its slotted end engaging the shaft 48 in the identical manner in which the crank I9 engages the same. When the link 69 has been operated through the crank 19 and attendant mechanism to draw the container material away from the clips 56, and sufficient of said material has been withdrawn for forming the package, the crank 92 will operate the rail 86 bearing down upon the idle roll 61, and will thus raise the gripping finger 51 releasing the container material.

Just prior to the operation of the crank 92 to release the container material, as just described, the container material is cut off at the point 93 by means of scissors which are shown in detail in Figure 5. These scissors whose blades 93' and 93 operate to out this material, have their ends provided with arms 94 and 94' which said arms respectively are provided with pins 95 and 95', which operate respectively in oblique long slots 96 and 96' respectively. These slots are contained in standards 91 mounted in a cross-head 98. These scissor blades have a bolt Hill which passes a slot Hill in the standard 91, and which is fastened into the lug I (see Figures 2 and 6) upstanding from the slit plate I in which the member 63 operates. The cross-head 98 at each end of the same has a pin 99 operating in the elongated slot llll of one end of rocker arms I02, whose pad I03 is pivotally mounted, as shown in Figures 4 and 'I. These rocker arms have their other ends pivotally connected at 1'4. Cranks l 06 whose lower ends have slots lll'l for receiving the stub shaft 5 have cam followers I08 and I08 to engage cams I09 mounted on said shaft .i for operating said cross-head to raise and lower the same, and thereby to open and close the scissor blades. This stub shaft ."a' is operatively connected to shaft 48. (See Fig. 4.)

The gripping fingers 51 and 51' are so timed that after the container material has been severed by the scissor blades, and the scissor blades then opened, said gripping fingers will pass between said blades and grip the end of the container material and draw the same outward as previously explained.

Plunger mechanism for placing container material In describing the formation of the container, only one operative mechanism will be discussed, but it will be understood that this mechanism for a large part is in multiple, and in the present illustration, it is intended that six of these containers be formed simultaneously.

The machine is provided with a cross-head I l I (see Figures 1, 2 and 4) which has its ends fastened to the tops of vertically reciprocating rods H2 and I i3. These rods are mounted in suitable bearings H4, 5, etc., and their lower ends are each provided with a link II6 having one end pivotally fastened thereto, while the other ends are respectively pivotally connected with cam arms II I and III, the former of which is provided with an idle cam following roll I I8 adapted to be engaged by the cam IIS while the other arm is provided with an idle camfollowing roller 9' adapted to be engaged by the cam I2I. These cams are both mounted on the shaft 48. The other ends of said cam arms I H are pivotally mounted at I22 in rigid depending brackets I23 mounted on the table frame 21. the cross-head III and in staggered relation are plungers I24 whose shafts I26 extend through said cross-head, and are provided with means, such as a cotter pin I21 at the upper end of the same for holding them in said cross-head while a spring I23 surrounds the shafts I26, and is held between the plunger I24 and the cross-head III. This spring is merely intended for the purpose of safety, and in case the plunger is prevented from entering the pocket I29 of the tray 68, as later discussed, will permit the said spring to be compressed and the plunger pushed upward. During ordinary working conditions, however, the tension of this spring is such that its presence is negligible.

The trays 68, each having as many pockets side by side as there are plungers I24, are intended to be fed into the machine, end to end, so that the longitudinal spacing between the pockets of the end rows of successive trays will be identical with the spacing between the longitudinal rows 01 pockets on an individual tray. By this method of location, a pocket will always be directly aligned beneath the plunger I24 and as the container material is formed and deposited into one series of staggered pockets, another series of staggered pockets will be immediately advanced for the next operation of the plungers. The mechanism for advancing these trays with their pockets will now be discussed prior to the discussion of the die mechanism for forming the container material into cups.

Tray advancing mechanism Referring now to Figures 1 and 9, each of the side frames 21 is provided with a slide rail I3I, while a cross-head I32 extends between said rails, and is slidable thereon. This cross-head has a groove I33 for receiving a shoulder I34 on the bottom of the tray advancing rail I36. This rail has lugs I31 equally spaced and between which the bottoms of the tray pockets will rest and engage these lugs for advancement through the machine,

The bottom of the cross-head is provided with a body to which the arm I35 of a crank is pivotally mounted. This crank is provided with a slot I35 in which the shaft 49 operates and the crank is also provided with cam followers I and I46 which are engaged by the cam I for reciprocating the cross-head I32.

The function of the lugged rails I36 and tray advancing plates I38 is as follows: The lugs on the rail I36 move the trays formed exactly the distance between the pockets of the trays, and when they have been advanced by virtue of the cross-head I32 with its operating mechanism, the tray raising plates I38 raise the trays and permit the return of the lugged rail to its original position, whereupon after the lowering of the tray raising plate I38, the trays may be again advanced the distance of one pocket by the operation of the advancing rail. The tray advanc- Mounted along ing rail I36 extends to the right hand standard at the front of the machine, as shown in Figure 1, so that the trays 68 may be fed from that point with their lateral edges contacting.

Referring now to Figures 4 and 8, the tray raising plates I38 are located between the advancing rails I36 and each of these plates contacts a portion of the bottoms of adjacent pockets. These plates are each provided with downwardly extending lugs I39 in which a set screw I4I prevents lateral movement thereof on the rods I42. A bell crank fulcrumed at I32 have their one ends engaging the rods I42 and their other ends connected with a connecting rod I44, while said connecting rod has an extension I46, while the end thereof is pivotally connected to one arm of a bell crank I4'I, while the other end of said link is pivoted to the arm I48 of a yoke I49, the outer end of said yoke being mounted on a stub shaft I 5!. The yoke arms are provided with idle rolls I52- and I53 which follow a cam I54 mounted on the shaft 49.

Bottom and side folding mechanism for container After the several pieces of container forming material have been severed by means of the scissors hereinbefore described, these pieces of material are centrally located above an oblique line of pockets extending transversely of the machine, and in accordance with the arrangement shown in Figure 2, that is to say, the material from the roll F will be centrally located over the rectangular opening G in the plate I56 aligned with a tray pocket also see Figure 6) while the severed material from the roll K will be centrally located over the opening M aligned with another pocket of the tray. Likewise a severed piece of container forming material from a roll between the rolls F and K, and not shown in Figure 2, will be centrally located over the opening P, which is aligned with a tray pocket between the pockets G and M. In like manner, severed sections of container material will be centrally located over the openings S, T and W. During the operation of the machine, each cycle thereof will place a severed piece of container forming material in the positions just described.

The plungers I24 carried by the cross-head,

In the description of the bottom and side forming means for the container, we will refer to one mechanism only, such for example as the plunger I24 shown in connection with the opening G in the plate I56 of Figures 2 and 6.

After the plunger has pressed the bottom of the material through the opening G in the plate I56, the bottom of said plunger carrying said material will pass downward betweenside plates I51 and I58 (see Figures 3, 4 and 10) and the material covered bottom of said plunger will first strike against the tongue I59, which is fulcrumed by the pin I6I in a bearing I62 of a bracket I63. Integrally formed with the tongue I59 are forming plate supports I64 to which the forming plates I66 are secured by screws I61. These forming plates I66 are separated by a distance substantially equal to the width of the side plate I56. As the bottom of the material covered plunger strikes the tongue I59, the same will be pushed downward and the forming plates I66 rotated about the pin I6I, so that the edges I66 of said forming plates, as they pass between the side plates I61 and I66 will engage the container material at the corner of the plunger and will first turn in the flaps I69 shown on the partially formed container illustrated in Figure 18.

As the plunger continues downward, after forming the fiaps I69, the edges I1I of said forming plates I66 will further turn the material against he plunger, so as to form the first side iiaps I12. During this last operation, the tongue I59 has been pushed entirely out of the space between the side plates I51 and I56.

It will. of course, be understood that the downward motion of the plunger I24 is uniform and continuous, although the several actions of the same are here independently described, that is to say there are no dwells in the plunger movements during the forming of the bottom and side flaps of the container.

Fastened to the side plate I56 by the screws I16 are transverse forming plates I14 which, as the plunger continues downward, will engage the flaps I 69 (see Figures 18 and 19) and will turn said flaps against the side fiaps I12 forming the flaps I16, as illustrated in Figure 19.

Continuing downward the plunger carrying the container material in the position shown in Figure 19, will strike with its bottom the tongue I11 normally extending between said side plates I51 and I56. This tongue I11 is fulcrumed by the pin I16 located in a bearing I19 of a bracket I6I secured to the side plate I51 by screws I62. Integraliy formed with said tongue are forming plate supports I63 to which the forming plates I64 are secured by screws I86. These forming plates I64 are separated by a, distance substantially equal to the width of the side plate I51. As the bottom of the material covered plunger strikes the tongue I11 the same will be pushed downward and the forming plates I84 rotated about the pin I16, so that the same will strike against the material shown at I81 in Figurerl9, and press the same over against the flap I12, so as to form the flap I86.

As the plunger continues downward carrying the partially formed container, as shown in Figure 20, it will pass directly into the pocket I29 of the tray 66, pushing said container so that its bottom rests in the bottom of said pocket, while the tray 66 is in its raised position on the tray raising plates I68 shown in Figure 4, and in detail in Figure 8. The cams II9 and I2I (see Figure 4) will now operate to raise the cross-head III, and thus withdraw the plungers from the pockets of the trays 66 up between the side plates I51 and I56, and to their normal positions, as shown in Figures 1, 3 and 4.

The plungers I24 are open at the top and bottom with the exception of where they are fastened to the rods I26, so that as the partially formed container of Figure 20 is pushed into the pocket I29 of the tray 66, the material firmly contracts the sides of said pocket and the plunger can be readily removed without disturbing the deposited container which is securely held therein by its closed bottom.

As the trays have the partially formed containers of Figure 20 deposited in the pockets thereof,

they are advanced step by step by means of the lugged advancing rail I36, and advanced under the hopper B, which is provided with material to be deposited in said containers, whose open top I69 (see Figure 3) extends above the top of the tray 66. This filling is accomplished with any type of predetermined quantity server, and the measured material passes downward through drop nozzles I9I which are aligned above the open top containers.

While the apparatus may, be employed for packaging many different materials in semi-liquid form and capable of being hardened, an illustration is that of cheese or the like wherein the cheese in semi-liquid form is deposited into a partially formed container taking the form of a receptacle, folded at its lower end and sides, and sustained in said form by the walls of a rigid pocket, and then folding the upper part of said receptacle to completely enclose the material therein.

The container forming material used for packaging cheese or the like would take the form of a double material wherein the inner material is waxed paper or the like and the outer material tin foil or the like.

After the partially formed containers with their open tops are filled with the material, they continue to advance in step by step movement, as before explained, advancing to the mechanism C for closing the same.

Mechanism for forming the top flaps to close the container Suitable bracket means I92 may be provided for carrying a shaft I93 on which the arm I94 is securely fixed. This arm is provided at its lower end with a shoe I96 as hereafter explained. An arm I91 integral with the link I96 is also securely fixed to said shaft I93. The lower end of the link is pivotally connected with a lever I99, which is reciprocated by cam means not shown and mounted on the shaft 49. The action of the mechanism just explained is as follows: When the tray 66 carrying the pocket X (Figure 1) has been moved by the lugged rail I 66 to a position just forward of the shaft I96, the lever I99, which has been holding the shoe I96 in a raised position, will be actuated through the cam on the shaft 49, so as to swing around and fold in the rear top portion of the container wall, as shown in Figure 13, thus providing the flap 26I resting on the surface of the material in the container cup (see Figure 21).

As the tray having the pocket X moves along in the direction of the arrow Z, the upper part of the front wall of the container will strike against a shoe 262 rigidly mounted by an arm 263 inthe bracket I92 and said end wall will thus be pressed inward onto the surface of the material, thereby forming the flap 264 shown in Figures 14 and 22. After passing from under the shoe 262, one side of the container extension will engage a shoe 266 rigidly mounted by the arm 261 on the bracket I92, so that upon movement of said tray, one extended side of said container will be pressed over onto the flaps 26I and 264 by the action of said shoe, thus forming the flap 266 (see Figures and 23). The container with its one side upstanding, as shown in Figure 15 next has said side engaged by the shoe 269 on the rigidly m'ounted arm 2, which whips said remaining side extension over onto the flap 266, thus forming the flap 2I2, as shown in Figures 16 and 24. The container now being completely closed, thus enveloping the material placed therein from the hopper B, has its upper flaps rolled down so as to permanently crease the same by means of. a rigidly mounted roller-2H shown in Figure 1. r

Of course, it will be understood that while the mechanism in connection with the apparatus C has been described as a single unit that in fact being as many of these units as there are plungers on the cross-head iii, the number, of course, is optional, and for convenience illustrated six- As the trays 68 pass from the apparatus they are lowered by any suitable means into a refrigerating tank D where the semi-liquid material in the containers is solidified, and after passing through said tank, the contraction of the material will permit the trays to be reversed, and the packages to readily fall from the trays when the same are turned upside down.

By the mechanism just above described, the operation of the entire apparatus is as follows:

The trays having been fed onto the tray raising plates I88 are intermittently advanced by the movement of the lugged rail I88 actuated by the cam I45 on the shaft 48. The material which forms the containers is fed in a roll form 8| by loop forming mechanism shown in Figure 3, and actuated by the shaft 48, and such container forming material passes through the clips 38 where it is grasped by the gripping fingers 5! and 51' by the rail 88 actuated by lever and crank mechanism from the shaft 48 to depress said roll 88 against the idle roll 61, thereby separating said gripping fingers. The container material is then severed by the scissors 93 at which time said severed pieces of material are located with their central parts immediately over the openings S, G, P, M, T and W in the plates I56.

The plungers I24 then engage the central part of this severed material passing the same down through the openings S, G, etc., where such material will assume the form shown in Figure 17.

Upon the continued downward stroke of the plungers I24, the material covered plunger will pass between the side plates I51 and I58 and the bottom of the plunger will first engage the tongue I58, thereby rotating the forming plates I88 to form the flaps I69 and I12 (see Figure 18).

Continued downward movement of the plunger causes the extended flap I89 to engage the transverse forming plates I14 which places therein the folds I'I8 as shown in Figure 19. Still further continued downward movement of I the plungers'results in their striking against the tongue I", thereby rotating the forming plates I84 which engage the extended sides I 81 and press the same down to form the folds I88.

Still further continued downward movement of the plunger deposits these open topped containers in the pockets I28 of the trays 68, whereupon the plungers are returned to their original raised position by virtue of the cams IIS and I2I operating the vertical rods H2 and H3 carrying the cross-head III upon which these plungers are mounted. Continued movement of the trays 88 caused by the reciprocating action of the lugged rail I36 passes the open top containers beneath the hopper B where they receive a predetermined quantity of semi-liquid material through the drop nozzles I8 I.

The material thus being deposited in the open topped container to the required height, and the trays continuing to move intermittently along the plates I38, the container passes beneath a raised shoe I88, where during the moment of its dwell, said shoe will be actuated through a cam operating a lever I88 to bring said shoe against the rearwall of said extended container, and bend the same down ontothe material in the container, thus forming the flap 28L Continued movement of the trays will cause the same to successively engage the shoes 282, 288

' and 209, where the front wall and two side walls respectively are bent down forming the flaps 204, 208 and M2, as shown respectively by Figures 22, 23 and 24. The closed upper part of the container is then rolled by the rigidly mounted roll 2l3, so as to press against said flaps "I, 204, 208 and 2l2, so as to give them a permanent crease.
